The proto-oncogene pituitary tumor transforming gene binding factor (PTTG1IP/PBF) is overexpressed in multiple tumours and associated with tumour progression. One of the tumourigenic processes that PBF can mediate is cell motility. PBF can induce cell invasion in both thyroid and breast cancer cell lines. However, in contrast to wild-type (WT) PBF, the Y174A PBF mutant was not able to induce the invasiveness of thyroid or breast cancer cells. The Y174 residue is highly phospho...
